Re: [Xen-devel] [PATCH][P2M] add printk to NP PAE logic in p2m

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

If we add that printk() then it's on a path triggerable by an HVM guest (via
the populate_physmap hypercall, for example) and there is a potential DoS
attack. The need to modify the Xen command line to enable NPT on PAE
hypervisor should really be caveat enough anyway.
